<h2>{{soil.Site_name}}</h2>
<h3>Introduction</h3>
<p>The soil investigation for the purposed {{soil.Site_name}} has been taken upon the request of {{soil.Submitted_1}} {{soil.Submitted_2}} {{soil.Submitted_3}}. The field soil investigation as per requirements was carried out on {{soil.Date_of_testing}} by the testing team of the institution  in the presence of {{soil.Presence_1}} & {{soil.Presence_2}} of the concerned department.</p>
<p>The purpose of this soil investigation was to determine the nature of the subsoil stratum and the safe net allowable bearing capacity of the soil.</p>

<h3>Field Soil Investigation</h3>
<p>Standard Penetration Test(S.T.P) was carried out at the proposed site for field soil investigation. The S.P test was carried out as per I.S Code 2131-1981 in the soil deposits at the foundation level or at an interval of 1.5m or at the location where change of soil strata takes place during the testing pricess. The samples of the soil both distrubed and tube were collected at the different depths and were  properly sealed in a air- tight plastic bag after labelling them carefully to maintain the moisture content for labortary testing.</p>

<h3>Laboratory Testing</h3>
<p>The various samples (disturbed and tube) collected during field soil investigation were tested in the laboratory (as per Standard Methods) for finding.</p>
<p>(i)	Grain size analysis and wet analysis</p>
<p>(ii)	Atterberg's limits</p>
<p>(iii) Field moisture content</p>
<p>(iv)	Bulk density</p>
<p>(v)	Direct/triaxial shear/Unconfined compression  tests</p>

<h3>Safe Bearing Capacity</h3>
<p>As per I.S. Code 6403-1981  the least of the following shall be taken as safe net allowable bearing capacity of the soil.</p>
<p>(i)	The safe net allowable bearing capacity from shear considerations is obtained by a dividing net ultimate bearing capacity by a suitable factor of safety.</p>
<p>(ii)	The safe net allowable bearing pressure that can be imposed on the base of the foundation without the settlement exceeding a permissible value is calculated either from settlement 	analysis or from the Standard Penetration Test Values (N) whichever is applicable depending upon the nature of sub soil strata.</p>

<h3>Underground Water Table</h3>
<p>The underground (i.e. sub-soil) water was {{soil.Water_table}} m at  the time of  field soil investigation.</p>

<h3>Proposed Structure/substructure</h3>
<p>The  substructure i.e. foundation of the proposed {{soil.Type_of_str}} is taken in the form of circular raft of diameter {{soil.Diameter_B}} to be laid at a depth of {{soil.Depth_D}} m.  Thus for calculations of raft foundation following data is considered.</p>
<p span style="padding-left:100px">Depth of  foundation = Df = {{soil.Depth_D}} m</p>
<p span style="padding-left:100px">Diameter of circular  raft foundation  =  B   = {{soil.Diameter_B}} m</p>
<p>The data obtained from the field soil investigation and the results of the laboratory tests have been used in the preparation of this soil investigation report.</p>
